Note

This is currently independent of ship mounting.

Definition at line 80 of file pilot_heat.c.

pilot_heatCalcOutfitC()

double pilot_heatCalcOutfitC

(

const Outfit *

o

)

Calculates the thermal mass of an outfit.

Definition at line 68 of file pilot_heat.c.

pilot_heatCalcSlot()

void pilot_heatCalcSlot

(

PilotOutfitSlot *

o

)

Calculates the heat parameters for a pilot's slot.

Definition at line 91 of file pilot_heat.c.

pilot_heatEfficiencyMod()

double pilot_heatEfficiencyMod	(	double	T,
		double	Tb,
		double	Tc
	)

Returns a 0:1 modifier representing efficiency (1. being normal).

Parameters

T	Actual temperature (K)
Tb	Base temperature for overheating purposes (K)
Tc	Max temperature for overheating purposes (K)

Definition at line 252 of file pilot_heat.c.

pilot_heatFirePercent()

double pilot_heatFirePercent

(

double

T

)

Returns a 0:2 level of fire, 0:1 is the accuracy point, 1:2 is fire rate point.

Definition at line 314 of file pilot_heat.c.

pilot_heatFireRateMod()

double pilot_heatFireRateMod

(

double

T

)

Returns a 0:1 modifier representing fire rate (1. being normal).

Definition at line 305 of file pilot_heat.c.

pilot_heatOutfitMod()

static double pilot_heatOutfitMod ( const Pilot *  p, const Outfit *  o  )

static

Gets the heat mod for an outfit.

Definition at line 121 of file pilot_heat.c.

pilot_heatReset()

void pilot_heatReset

(

Pilot *

p

)

Resets a pilot's heat.

Parameters

p	Pilot to reset heat of.

Definition at line 110 of file pilot_heat.c.

pilot_heatUpdateCooldown()

void pilot_heatUpdateCooldown

(

Pilot *

p

)

Overrides the usual heat model during active cooldown.

Parameters

p	Pilot to update.

Definition at line 262 of file pilot_heat.c.

pilot_heatUpdateShip()

void pilot_heatUpdateShip	(	Pilot *	p,
		double	Q_cond,
		double	dt
	)

Heats the pilot's ship.

The ship besides having conduction like in pilot_heatUpdateSlot it also has radiation. So now the equation we use is:

q = -k * dT/dx + sigma * epsilon * (T^4 - To^4)

However the first part is passed as parameter p so we get:

q = p + sigma * epsilon * (T^4 - To^4)

sigma being the Stefan-Boltzmann constant [5] = 5.67×10−8 W/(m^2 K^4) epsilon being a parameter between 0 and 1 (1 being black body) T being body temperature To being "space temperature"

Parameters

p	Pilot to update.
Q_cond	Heat energy moved from slots.
dt	Delta tick.

Definition at line 229 of file pilot_heat.c.

pilot_heatUpdateSlot()

double pilot_heatUpdateSlot	(	const Pilot *	p,
		PilotOutfitSlot *	o,
		double	dt
	)

Heats the pilot's slot.

We only consider conduction with the ship's chassis.

q = -k * dT/dx

q being heat flux W/m^2 k being conductivity W/(m*K) dT/dx temperature gradient along one dimension K/m

Slots are connected only with the chassis.

Parameters

p	Pilot to update.
o	Outfit slot to update.
dt	Delta tick.

Returns

The energy transferred.
